Ajax stop/Ajax start works only the first time either button is clicked after the page is loaded, and I can't see why. If either button is clicked after the initial click, the loading div does not appear. I would like to show the loading div whenever I click either the Click 1 or Click 2 button and for the div to disappear once the contents have been fully loaded. Please see the code below:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#loading').hide().ajaxStart( function() {
$(this).show();
}).ajaxStop ( function(){
$(this).hide();
});
$(document).on('click', '.menu1', function(){
$('.maincontent').load("1.php");
});
$(document).on('click', '.menu2', function(){
$('.maincontent').load("2.php");
});
});
</script>
<style>
#loading {
width: 100%;
height: 100%;
top: 0;
left: 0;
position: fixed;
display: block;
opacity: 0.7;
background-color: #fff;
z-index: 99;
text-align: center;
}
#loading-image {
position: absolute;
top: 25%;
left: 50%;
z-index: 100;
}
</style>
</head>
<body>
<button class="menu1">Click 1</button>
<button class="menu2">Click 2</button>
<div class="maincontent">
<div id="loading">
<img id="loading-image" src="images/ajax-loader.gif" alt="Loading..." />
</div>
</div>

I am new to javascript and jquery so I'm not sure where to start.
I am working on a project and it would be nice if the page can auto-scroll into a certain viewport after the user has been inactive for a few seconds.
This can be seen in https://www.nfrealmusic.com/#store when it auto scrolls to a specific section on load up and completes your scroll when you scroll down alittle bit more in between the "merch" and "music" section.
<!DOCTYPE html>
<html>
<head>
<style>
#myDIV {
height: 250px;
width: 250px;
overflow: auto;
background: green;
}
#content {
margin:500px;
height: 800px;
width: 2000px;
background-color: coral;
}
</style>
</head>
<body>
<p>Click the button to scroll to the top of the element with id="content".</p>
<button onclick="myFunction()">Scroll</button>
<div id="myDIV">
<div id="content">
Some text inside an element.
</div>
</div>
<script>
function myFunction() {
var elmnt = document.getElementById("content");
elmnt.scrollIntoView();
}
</script>
https://codepen.io/Fullstack_developer/pen/bGGKNJX
would like for it to scroll into view automatically without having to press a button!
can this be done with jquery or velocityjs?
Thanks for your help!
function myFunction() {
var elmnt = document.getElementById("content");
elmnt.scrollIntoView();
}
#myDIV {
height: 250px;
width: 250px;
overflow: auto;
background: green;
}
#content {
margin: 500px;
height: 800px;
width: 2000px;
background-color: coral;
}
<body onload="myFunction()">
<p>Click the button to scroll to the top of the element with id="content".</p>
<button onclick="myFunction()">Scroll</button>
<div id="myDIV">
<div id="content">
Some text inside an element.
</div>
</div>
</body>
You call scroll automatically using this way:
window.onload = function(e){
var elmnt = document.getElementById("content");
elmnt.scrollIntoView();
}
With jQuery, you can use .animate() to scroll without pressing button as shown below:
$(document).ready(function(){
$("#content").animate({ scrollTop: "300px" });
});
window.onload = function(e){
var elmnt = document.getElementById("content");
elmnt.scrollIntoView();
}
#myDIV {
height: 250px;
width: 250px;
overflow: auto;
background: green;
}
#content {
margin:500px;
height: 800px;
width: 2000px;
background-color: coral;}
<!doctype html>
<body>
<p>After loading, it will automatically scroll to the top of the element with id="content".</p>
<div id="myDIV">
<div id="content">
Some text inside an element.
</div>
</div>
</body>
</html>
I am totally new in jQuery. I am trying to show a loader before all my page content is ready.
<script>
$(document).ready(function(){
$(document).ajaxStart(function(){
console.log('wait');
$("#wait").css("display", "block").show();
});
$(document).ajaxComplete(function(){
$("#wait").css("display", "none").hide();
});
});
and in body i have this,
<div id="wait" style="display:none;position:absolute;top:20%;left:50%;"><img src="{{ asset('assets/global/img/ajax-loader.gif') }}" /></div>
but no loader is displayed and no error shows in console.
Can anyone give me any solution or example regarding this?
Thank in advance!
Check Demo Code Below.
$(document).ready(function(){
$('#loader').fadeOut(showBodyPart);
function showBodyPart(){
$('#body_parts').fadeIn(300);
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="loader">
<img src="http://i.imgur.com/KUJoe.gif" id="a" alt="Loading" />
Loading...
</div>
<div id="body_parts" style="display: none;">
<p>If you click on me, I will disappear.</p>
<p>Click me away!</p>
<p>Click me too!</p>
</div>
With Bootstrap 4, Jquery, CSS
<style>
.overlay {
position: absolute; background-color: white; top: 0; bottom: 0; left: 0; right: 0; margin: auto; z-index: 10;
}
.overlay div{ position: relative; z-index: 10; top:30%; left: 50%;}
</style>
HTML
<body>
<div class="overlay">
<div class="spinner-border text-secondary" >
<span class="sr-only">Loading...</span>
</div>
</div>
<div> Helloo World</div>
</body>
JQuery
<script>
$(window).on('load', function(){
$( ".overlay" ).fadeOut(100, function() {
$( ".overlay" ).remove();
});
});
</script>
This is what I have so far
This is the code that I used to get this image on there:
<!DOCTYPE HTML>
<html>
<head>
<link rel="stylesheet"type="text/css"href="index.css"/>
<title>My Title</title>
</head>
<body>
<div class="slider">
</div>
</body>
</html>
and here is the CSS I used for my div "slider" class
.slider{
background-image: url('images/background.png');
height: 100%;
width: 50%;
position: absolute;
background-repeat: no-repeat;
}
So how can I make a div INSIDE of this div, which will allow me to display a slideshow of my app's images? I want it to be very similar to these websites:
shazam.com
instagram.com
venmo.com
I don't know how to fit these images the right way, can somebody please help?
If I understand you correctly, you are talking about something like this
JSFiddle Demo
var $canvas
$(function(){
$canvas=$("div.canvas")
setInterval(scroll, 5000);
});
function scroll(){
if ($canvas.position().left!=-1195){
$canvas.animate({left: "-=239"});
}else{
$canvas.animate({left: 0});
}
}
.mask {
position: absolute;
left: 31px;
top: 122px;
width: 239px;
height: 342px;
overflow: hidden;
}
.canvas {
position: relative;
width: 2195px;
height: 342px;
}

I cannot make a simple click event on the "canvas" using JQuery click function.
$(document).ready(function(){
alert("test");
$("#canvas").click(function(){
alert("canvas");
});
$(".middle").click(function(){
alert("middle");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle">middle
<div id="canvas">canvas</div>
</div>
"test" message is appearing but functions above is not working. Other siblings of div "middle" (I did not include since I tried to remove them for testing and it still happening) can execute events but only this div and inside cannot execute a single event.
Tried also to console.log($("#canvas")) and it fetches some data below.
[div#canvas]
here is the complete html:

Below is the image of the divs:
This is really frustrating because this is a basic function that I cannot call.
Edit:
I added a https://jsfiddle.net/5mtt2khu/
Please let me know any questions.
Thanks!
Do with event.target element .And match with condition
Updated js Fiddle
$(document).ready(function() {
alert("test");
$(".middle").click(function(e) {
if($(e.target).attr('id')== 'canvas'){
alert('canvas')
//do stuff for canvas
}
else{
alert("middle");
//do stuff for middle
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle">middle
<div id="canvas">canvas</div>
</div>
Updated
Remove or change the z-index
$(document).ready(function() {
alert("test");
$(".middle").click(function(e) {
if ($(e.target).attr('id') == 'canvas') {
alert('canvas')
//do stuff for canvas
} else {
alert("middle");
//do stuff for middle
}
});
});
.middle {
z-index:0;/*remove or change > -1*/
position: relative;
display: block;
height: 88%;
width: 100%;

Your code seems to work.
So the problem must come from other things. Here is some possibilities :
JQuery is not correctly installed
You have a javascript error before so this is never executed
Your html is dynamically added after you load the event handler
You have an other div with the same id somewhere
If your html is dynamically added, I recommend you to do something like this
$(document).ready ( function () {
$(document).on ("click", "#canvas", function () {
alert("canvas");
});
$(document).on ("click", "#middle", function () {
alert("middle");
});
});
If you have several "canvas" id, you can do something like :
$("[id=canvas]").click(function () {
alert("canvas");
});
I think you are looking for something like this:
$(document).ready(function(){
alert("test");
$("#canvas").click(function(e){
alert("canvas");
e.stopPropagation();
});
$(".middle").click(function(){
alert("middle");
});
});
.middle {
width: 200px;
height: 200px;
background: red;
}
#canvas {
width: 100px;
height: 100px;
background: green;
margin: 50px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle">
<div id="canvas"></div>
</div>
Hope it helps :)

Try to change the div to input type or button.It works when I specified the color to the div and clicking it.So, without knowing where to click the event was not working.
Your jQuery code is actually working fine as it should. The problem here is propably because the canvas has no height and width defined, so it's too small to actually be able to click on it.
Give the divs a height and width like the below code snippet and you'll see that the jQuery gets executed correctly.
$(document).ready(function(){
alert("test");
$("#canvas").click(function(){
alert("canvas");
});
$(".middle").click(function(){
alert("middle");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle" style="border: 1px solid black; height: 50px; width: 100px;">
<div id="canvas" style="border: 1px solid red; height: 15px; width: 30px;"></div>

Ok, I am creating a landing page, where what I want to happen, is the page split in half, and either side slide off of the screen, and the main page is left. I almost have it, but what the right side is doing, is whenever the window is at certain sizes, it is going below the left side. I'm not sure quite how to fix this, and everything I try doesn't really work, and there I haven't been able to find any answers online. Thanks for any help
